Do you know which type (order code, source etc) is used on the Arduino Nano? It's a tiny part, smaller than the oscillator packages I found on the internet. So if someone could turn me in the right direction, I would be indepted.
Also reading the other threads dealing with a similar topic, do I need to include caps in combination with the 16MHz osc?
Its a resonator, not an oscillator. Ceramic resonators integrate all the load capacitance needed, as opposed
to quartz crystals where they are provided externally (almost always).
